| | Abstract | | For near-surface applications, ground-penetrating radar (GPR) commonly employs relatively higher frequencies in order to achieve higher resolution. However, higher frequencies also make results of GPR measurements sensitive to soil heterogeneity. As a result, the performance of GPR can strongly depend on the soil heterogeneity in permittivity, which seems the most influential factor compared to other influencing properties. This paper illustrates the influence of heterogeneous soil on the performance of higher frequency GPR with an example in landmine detection application. |
